Beschreibung
Zusammenfassung:	The present invention provides an aramid nanofiber (ANF)-based insulation paper and a preparation method thereof, and relates to the technical field of composite insulation material. The ANF-based insulation paper provided in the present invention includes ANFs and inorganic insulation materials. The ANFs have a bifurcated geometry and form a three-dimensional network structure, and the inorganic insulation materials are distributed in the three-dimensional network structure. The ANF paper provided in the present invention, with optimal electrical and mechanical properties and excellent insulation and flame-resistance, can replace mica tapes, aramid papers and aramid mica papers on the current market for insulation, and thus the thickness for insulation can be reduced. The present invention provides a method for preparing the ANF-based insulation paper. The preparation method provided in the present invention is simple, has excellent operability, and can be used for continuous preparation, thereby facilitating the realization of industrial production.
